Hi,

My friend just picked up a 00 Civic SI block (B16A2) and it's gong to need some work. The block was sitting in the rain for a few months (totaled car...someone stole the head... and left the hood off ) Anyway two of the cyilinder walls have some rust on them & on the top of the pistons... I'm thinking that the block will need to be bored out some. Does anyone have any suggestions on what the bor should be... and what pistons/rings we should use... We don't want to go nuts on the block....I mean $$$ wise, and crazy compression, because we might throw in a small turbo setup in the future... We're going to use a stock B16A2 SI head... Thanks

 

First thing you need to do is detemine if you want to go allmotor or turbo and what the car will be used for. Then we might be able to help you out.

But the sleeves will at least need to be honed to clean it up.

 

Hi,

We want an all motor setup, but we don't want to go so crazy that a small turbo would be out of the question in the future... Basicly... we don't want to go to high in terms of compression, on the block.... Thanks.

 

Well just run the stock b16 pistons and you will be able to run a small turbo setup like a greddy or something. If you want to up the compression a little more and run N/A then you might want to consider the CTR piston setup.

Like I said before you need to make up you mind on which way you want to go N/A or Turbo.

 

if you are going with a slight overbore, I suggest some oversized cp pistons at 10.5 compression raio. Let me know if you need them.

 

Hi... If we hone/bore out the walls because of the surface rust, can we still use the stock pistons? What would you recomend for a hone/bore size... That's the whole reason why we're debating a different piston setup. Is there a happy medium... good power whlie your in the N/A, but if Santa brings you a greddy turbo it would be okay to slap it on, and make over 200 whp... Thanks guys.

Unless you know some damn good tuners, I doubt you can go much higher than 10:1 compression and still slap a turbo on it. 10.5 may be possible, but probably not too safe. You really, really need to determine if you wanna go all motor or turbo. I would say just keep the block around until you know for sure what you want to do. If you're gonna do it, do it right the first time.

You might as weel keep it at stock compression and if later putting a turbo on, use like a cosmetic headgasket to lower the compression or find a good tuner and safely run 8-10psi of boost.

Fuel management and tuning = key.

 

10.5 is too fine for turbo as long as you tune it. But even on na, you still want to tune. Remember type r compression is 10.6. If you bore out the walls, you will need to go with overized pistons. I have some new .5 oversized pr3 pistons also. Let me know.
